Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
This afternoon: Mostly sunny and cold, but not quite as cold as yesterday with a high around 30.
Tonight: Clear and seasonably chilly with a low from 20 to 25.
Friday: Mostly sunny and milder with a high from the upper 30s near the bay shore to the mid 40s inland.
Friday Night: Variable cloudiness with a low in the upper 20s.
Saturday: Mostly sunny and mild with a high from the mid 40s near the bay shore to the lower 50s inland.
The extended outlook calls for clouds and sun on Sunday with a low in the mid 30s and a high in the mid to upper 50s (except upper 40s to lower 50s along the bay shore.) Mostly cloudy on Monday with a chance of mixed precipitation. The low will be in the lower 30s and the high will be in the upper 30s. Mostly cloudy on Tuesday with a low in the lower 30s and a high in the lower 40s. A chance of rain on Wednesday with a low around 35 and a high near 45.
One of the coldest mornings in many years was experienced from Tidewater in Virginia to the Delmarva peninsula with temperatures at many locations below zero (including -6 degrees at Salisbury, Maryland; -6 degrees at Ocean City, Maryland; and -6 degrees at Wakefield, Virginia. Other locations reported temperatures around zero or the single digits. These cold temperatures resulted from high pressure, a clear sky overhead, light winds, and fresh snow that enhanced radiational cooling. As the center of high pressure moves offshore this afternoon and evening, a more southerly flow will result in a rebound of the mercury with afternoon highs closer to the freezing point. The flow of air from the south will become more pronounced on Friday with highs breaking above the 40-degree mark, and on Saturday with highs approaching 50 at some locations a few miles inland from the bay (icy cold waters will hold down shore locations in the 40s). Meanwhile, a cold front will move from west to east across the bay later in the weekend and into early next week. Waves of low pressure are expected to move across the stalled frontal system and produce mixed precipitation on Sunday night into Monday. The long-range calls for milder temperatures with a chance of rain by the middle of next week and then colder, stormier conditions by the following weekend.
